I don’t know how to approach a girl I’m seeing.

Hi, so it’s a little complicated, we meet several times a week for at least 6 months at the bus stop. I know her instagram but I don’t know if it’s better to reach out to her in person but I don’t know if I have the balls to because l’ll be talking to her for the first time so something awkward might happen but if I write to her on instagram l’II look like a p***y for not reaching out personally, moreover, if I just write to her, there will be that awkward time when you don’t know whether to say hello or something

TLDR: Don’t know if I should reach out this girl personally or just to text her
